IPC: A47J27/21
Filed: 2002-05-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric water heater capable of ensuring the reduction in power consumption and the safety in water supply, and enhancing the safety for inclusion of foreign matters or turnover.  <P>SOLUTION: This electric water heater has a water heating container 6, a heating means 8 for heating liquid in the water heating container, a water storage container 1 for receiving the liquid to be supplied to the water heating container, and a supplying passage 5 connecting the water heating container to the water storage container. The water storage container has a lid 13 for covering it, and the water storage container has a lock means (lock handle 15) for liquid-tightly locking the lid to the water storage container. According to such a structure, only a necessary quantity of liquid can be heated and heat- retained in the water heating container to reduce the power consumption, and the safety in water supply can be ensured since water supply can be performed to the water storage container. Further, the safety for inclusion of foreign matter or turnover can be also enhanced by the lock means with the lid of the water storage container.  <P>COPYRIGHT: (C)2004,JPO
